FRAME FOR RAILWAY ROLLING-STOCK.

Patented Sept. 4, 1906.

Application led January 22, 1906. Serial No. 297,338.

.To all whom it may concern,.-

Be it known that I, THOMAS E. ADAMS, a citizen of the United States, residing at Pine Bluii, Jefferson county, Arkansas, have invented a certain new and useful Improvement in VFrames for Railway Rolling-Stock, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to W `ch it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which* 'gure 1 is a plan view of my im roved frame. Fig. 2 is a sectional view on t e line 2 2 of Fig. 1. Fig. 3 is a sectional view on the line 3 3 of- Fig. 1. Fig. 4 is a detail view of'one of the longitudinal sill members. Fig.

5 1s a detail view of one of the end sills inverted. Fig. 6 is a longitudinal vertical sectional view through a modified form of boxcasting forming the coupling-mount between the tender-frame and locomotive. Fig. 7 is a cross-sectional view through the same on the line 7 7 of Fig. 6, and Fig. 8 is a modified form of end sill and method of connecting the longitudinal sills thereto.

his invention relates to a new and useful improvement in frames for railway rollingstock, the same being particularly designed as an improvement in frames for tenders of locomotives, although it is obvious that the same is useful in connection with different types of cars, such as box, flat, gondola, &c. The objects of my resent invention are to employcast-steel as t e material of which the principal parts of the ame are composed, said parts being interlocked and secured to.- gether in such manner as to add to the strength and rigidity of the frame in addiy rear en tion to the connecting-rivets or other fastening devices such as are usually employed. With these objects in view the invention consists in the construction, arrangement, and combination of the several parts, all as will be hereinafter described, and afterward pointed out in the claims. i

a tender-frame the two ends are usually provided with different ty es of coupling devices, the end toward the lbcomotive having a draft-pocket for the rece tion of a link-andpin cou 1er, while the other end, being the provided with an et for cooperation of the A frame, is

approved form of pock with various styles of draft-rigging in common use, with which may be employed the well-known type of J anney coupler. l indicates the end sill of the frame, which is nearest the locomotive, said end. sill,`as"

shown in Fig. 5, being in the form of a casting strengthened by transversely-disposed webs, the bottom of the end sill being preferably left open. The inner side wall of the end sill is provided with notches or recesses 2, which are designed to receive the vert-ical Webs 3 of the longitudinal sill The ends of these sill members where the extend into the end sill 1 are provided with7 heads 5, strengthened by flanges, as shown in Fig. 1 which heads are riveted to the outer walls of the end sill 1. The webs 3 of the longitudinal sills are preferably provided with integral flanges 6, as shown, forming substantially a channel-shaped structure, although it is obvious that these flanges may be extended on both sides of the web to produce an I-shaped structure.

The opposite ends ofthe longitudinal sills are provided with enlarged heads 7, which are fastened to the end sill 8 by suitable rivets. End sill S is preferably a casting shaped similar to sill 1, except that the notches or recesses 2 are omitted and the longitudinal sills do not "inner wall of' the sill.

9 indicates through bolts which pass through the end sills and the heads of the central longitudinal sills, said bolts or rods having nuts on their outer ends impinging against the outer faces of the end sills or other parts secured thereto-such, for instance, as the buffer-block 10 secured to the outer face of the end sill 1. Rods 9 act asV tie-rods and serve to add rigidity to the structure in the transmission of pulling and buiiing strains.

1 1 represents plate-bars whose ends are bent and riveted to the end an d side sills, as shown, said bars extending diagonally inwardly and being riveted to the vertical Webs of the center sill and thence diverging outwardly and bent with their ends riveted to the side sills.' These diagonal braces give considerable strength to the frame and resist twisting and torsional strains. A tie-plate 12 is preferably arranged across the center of the frame and riveted to the side and center sills to resist any bulging tendency of the side and center sills at this point.

13 represents the holsters, preferably made of cast-steel, which bolsters, as shown in Fig. 3, are formed with shelf-like projections at their ends extending under the side sills, while upward extensions 14, near the ends, are riveted to the vertical webs of the side sills, said upward extensions being reinforced by 'strengthening-flanges, as shown. Vertical Webs 15 also extend upwardly from the center of the bolster and are riveted to the center sills, the same set of rivetsbeing employed for this connection as are used to secure the diagonal brace-plates 11 in position at this point.

16 indicates a box-casting formin the coupling-mount between the tenderame and locomotive, which casting, as shown in Fig. 1, is provided with laterall -extending flanges resting upon the to s ofY the center sills, said flanges serving to old the casting in position between the center sill. The casting 16 extends rearwardly and abuts against the bolster and its upwardl rojecting webs 15, the vertical side Walls ofytlrie casting being riveted to the webs of th center sill, as shown.

17 is a casting constituting a mount for the draft-rigging at the rear end of the tenderframe, said casting also having flanges 18, which rest upon the tops of the center sills, the vertical walls of said casting lying adjacent the webs of the center sills and being riveted thereto. Casting 17 fits between the end sill and the bolster, said casting abutting against the web 15, extending up from the bolster. When castings 16 and 17 are arranged in position, they are introduced from the top of the -underfra1ne, and When the tender is in place there is no chance for the castings to work loose or become displaced.

While I have shown the main arts of my underframe as being made up o castings, it is obvious that rolled or built-up structures could be employed in lieu of castings, if desired.

In Figs. 6 and 7 I have shown a modified form of box-casting 16, which forms a mount for the coupling device between the tender-frame and the casting is provided with laterally-extending flanges extending above and below the center sills, said casting extending rearwardly and abutting against the bolster.

In Fig. 8 I have shown a modified form of end sill, in which the connectin -webs extend inwardly from the end sill, tow 'ch the longi- `tudmal members Ina-y be riveted. By the use of this construction the longitudinal members may be made of commerciallyrolled beams.

I am aware that minorchanges in the construction, arrangement, and combination of the several parts of my device can be made and substituted for those herein shown and described Without in the least departing locomotive, which from the nature land principle of my invention.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is-

In a frame for railway rolling-stock, the combination With end and center sills, of a bolster having vertical extensions between the center sills and secured thereto, and a casting constituting a mount for the draft appliances, said casting having laterally-extending ilanges resting upon the tops of the center sills, and said casting abutting at its gitudinal sills connected to said end sills, cast bolsters having vertical extensions secured to said longitudinal sills, longitudinal tie-rods connecting the end sills, and diagonal braces ter connecting the side and cen ongitudinal sills and extending from end sill to end sill;

substantially as described.

In testimony whereof I hereunto aflix my 3o signature, in the presence of two witnesses, this 1 1th day of January, 1906.
